What the heck are those sponsors??

Maybe this is a dumb question but I'm sort of new to the sport. So everyone knows what USPS is, but what are some of those other major sponsors? I mean I see these names but I have no idea what kind of business(or whatever) these are. I assume they are mostly(all?) European. For example, ONCE, Adecco, Lotto, KELME, Telekom, Robobank, COFIDIS, DOMO, etc, etc, etc..........

Hey that's cool. I think there was a pic floating around of a Dekker ad in a bank lobby (Rabobank, of course!).
I always thought Credit Agricole was an agricultural bank! Don't they have a wheat stalk in their logo?
